As per thread title, are standard wastegate actuators still readily available for the standard turbos as the bodies on mine have corroded (one right through!) so they both need replacing! I know you can get 2nd hand, but I'd rather not go there as I want them to last (just incase I hang onto the car!), I also know you can get alloy ones too but I dunno as I wanna spend £230 to get em & I'm not really bothered about being able to open them up and have different springs for higher boost etc. I will obviously strongly consider the alloy ones if o.e ones are nearly the same money as obviously they WILL last longer, but I'd like to think that o.e actuators will be a good bit cheaper! Thing is I seem to recall reading/ being told that o.e actuators have become nla and you either have to 2nd hand or alloy!!!

Can you guys please clarify this one for me please so I know exactly what all my options are before I shell out! Lastly where would be the best place to source o.e actuators ( assuming there available!) lotus factory themselves??

Sorry if ive asked this before (don't recall doing!)

Cheers Matt.

Hi Matt,

The OEM ones are over £235 each x 2 = £470 which is why I used to supply the alloy ones. These are better, last longer and are half the price of the OEM ones. If you think of it as £115 each then they don't sound too bad.
I can still get them if you want them, drop me a pm. I gave a set of used OEM ones to North West Lotus about a month ago. You could try them if you can't afford new ones?

The part number is A918E6078S from Lotus or now the new number is C918E6078S

If you don´t want to go to an aftermarket alloy actuator, then you can use these

Standard T2 wastegate actuator

You will still need to re-use your screw-on rod and set-up the actuators to the Lotus mechanical boost setting.

Guys your BOTH legends in my book!

Thanks to you both for the quick replies!!

Dave - if you can still get the alloy actuators then (pending the answers to the next questions) i'll probably be PM'in you soon to get some off ya buddy! Basically what i want to know is :-

1) Are these alloy actuators just a straight swap for the o.e items or do they require any "work" to get them to fit??

2) Are they "fit and forget" items too, As in are they pre-set to lotus o.e specs or will they need fitting and adjusting!???

Cheers Matt!

Hi Matt,

They are a straight swap although because the OEM has floating bolts as opposed to the alloy actuators with fixed bolts, sometimes you have to drill the holes to one of your brackets to the next size up. When I fitted mine they went straight on but some owners experienced problems and had to open up their mounting holes. Only took another 5 mins.
As for setting up, providing you go for standard springs then the setup is the same as the Lotus technical manual.
Mike's Ebay link looks like a good buy too, so check it out and do you sums before buying. The Fiesta ones are ever so slightly different to the Lotus one whereby you have to kink the actuator rod a bit more. Sometimes you can get away with no alterations at all.

Ok Dave cheers again bud!

As for getting hold of the relevant info we'll need to set them up (the Lotus technical data), Do you know where we can find that????

[blue harbour]

Can someone please advise WHAT the setup procedure is for new actuators please as i will soon hopefuly be attempting to replace both the actuators with some nice new alloy ones (courtesy of Dave - thanks buddy!), and i want to get it right 1st time, and not be potentially over/under boosting!

Will the setup require purchasing any special tools??

Cheers Matt!

Old actuators are well knacked, and atleast one may well have not been working at all recently as the diagphram looked to have gone!

[blue harbour]

Just a wee bump of sorts, But as above What is the proper setup procedure for the actuators please!?

We've got the alloy actuators fitted in place, and have roughly "guessed" how to set them (the rod end is adjusted so it's "just" holdding the wastegate shut! - or so we think anyway!

I tried without luck to source a hand pressure pump with gauge yesterday so we could pressurise the capsule with 5psi and see if the actuator rod moves, but tbh I have no idea "how much" it's supposed to move when it does, and what the correct procedure for setting them up is anyway!

If we get done today i did have plans on taking the car out and gingerly winding her up bit by bit to see what boost levels we hit, but even if we do manage 0.35bar or whatever it's supposed to be, then were not gonna know whether that's balanced across both sides equally or not!

Push comes to shove i'd like to think i could actually drive the car to a specialist and get the wastegates properly setup there - just to be sure!

Cheers Matt!

Hi Matt,

Someone desperately needs to get themselves and owners manual

To set the wastegates up for the correct mechanical base boost, you will need a dial gauge and some way of apply calibrated pressure to the wastegate capsule.
Make sure that you have the standard green spring fitted in the aftermarket wastegate capsules.

You will be looking to position the dial gauge rod horizontally along the direction of the actuator arm. You´ll need to fit the dial gaugein position to accurately measure the movements. Oncee in position, zero the gauge and start to apply pressure slowly to the capsule. Adjust the length of the wastegate actuator rod (1/2 turn increments), until you have 0.4mm (0.015") with 4.9-5.2psi.

Job done.

Cheers,

Hi Mike,

You're right i suppose i could do with getting hold of a w/shop manual, But due to the fact that i'd have to buy new kit to set the actuators up i think i'm gonna simply take the car to a specialist n let them do it!
